how to add fasteners in solidworks assembly


SolidWorks is the go-to software for creating 3D models and designing industrial parts for a wide range of industries. Creating an assembly with SolidWorks is extremely easy, and you can add various elements and fasteners to the assembly to make it more efficient and functional. Adding fasteners in SolidWorks assembly is a vital part of designing, as they add stability and strength to the model. In this article, we will discuss how to add fasteners in SolidWorks assembly.

Understanding Fasteners in SolidWorks Assembly

Before you start adding fasteners in a SolidWorks assembly, it is essential to have a basic understanding of what fasteners are and how they work. Fasteners, commonly known as screws or bolts, are essential components in any assembling process. They hold two or more parts together, providing stability and strength to the assembly. Fasteners come in various sizes, shapes, and types, and choosing the right fastener for your assembly is crucial.

Selecting the Correct Fastener

Choosing the right fastener is a crucial aspect of the designing process. You need to determine which fastener is suitable for your assembly, depending on the application and the material you are using. Selecting the correct fastener requires an examination of three critical characteristics: the length, the diameter of the thread, and the thread pitch.

The first step to choose the right fastener is to determine the length of the fastener required. To do this, measure the combined thickness of the material that you want to fasten, and add the depth of the hole to be drilled to hold the fastener. Remember, a fastener that is too long can cause structural problems and may protrude out of the material, causing a safety hazard.

The next aspect to consider is the diameter of the thread. The diameter of the thread determines the tensile strength of the fastener. If the fastener is too narrow, it may break under tension or allow the materials to loosen gradually. If the fastener is too thick, it may not tighten securely.

Lastly, you need to consider the thread pitch of the fastener. Thread pitch refers to the distance between the threads. Thread pitch is determined by measuring the distance between two threads and dividing this by the diameter.

Adding Fasteners to SolidWorks Assembly

Once you have chosen the correct fastener for the job, adding them to your SolidWorks assembly is simple. Follow the instructions below to add fasteners to a SolidWorks assembly.

1. Open the assembly file in SolidWorks.

2. From the Toolbox, select Fasteners from the Hardware tab.

3. Use the search function to find the fastener you require.

4. Drag and drop the fastener onto the component where you want it to go.

5. You can then manipulate the fastener to align it as required.

6. Once you are satisfied with the position of the fastener, click on the green tick to save it.

7. Repeat the process for each fastener you need to add.

Best Practices for Adding Fasteners

When adding fasteners to a SolidWorks assembly, there are a few best practices that you should follow. Firstly, it is essential to select fasteners that are compatible with the material you are using. If the material is soft or brittle, use a fastener with a shallow thread pitch to prevent damage to the material. For harder materials, use a fastener with a deeper thread pitch to ensure that it bites into the material and forms a secure hold.

Secondly, when adding fasteners to an assembly, it is important to follow the correct sequence. Start at one end of the assembly and work your way to the other end, inserting fasteners as you go. This will help to maintain symmetry within the assembly and prevent the material from warping or bending.


Adding fasteners to a SolidWorks assembly is a vital part of designing a functional and stable model. By following the techniques we have discussed, you can ensure that you choose the appropriate fasteners for your assembly and add them correctly. Whether you are a novice or an experienced SolidWorks user, adding fasteners to an assembly is easy, and the results are well worth the effort.
